摘 要：Variable temperature infrared spectra(3500 to 400 cm)of krypton(-105 to-150℃)or xenon(-60 to-100℃)solutions of vinylsilyl fluoride(CH=CHSiHF),vinylsilyl chloride(CH=CHSiHC1)and vinylsilyl bromide(CH=CHSiHBr)have been *** these data,the enthalpy differences between the more stable and the less stable rotamers have been determined to be 59±12 cm(0.71±0.15 kJ/mol),78±11 cm
